He married Margaret Wainhouse after 1752. Margaret was born about 1710. Margaret was the daughter of
Francis Wainhouse and Patience "V". Margaret died 1768 in Northampton Co., VA, at 58 years of age. She made
a will in Northampton Co., VA, April 11, 1768. (James H. Marshall, Wills & Admin. of Northampton Co., VA, p. 415)

Margaret's will was probated in Northampton Co., VA, September 13, 1768. Thomas Marshall was named guardian to Margaret and
presented inventory and appraisal 3 February 1724, Accomack Court. Court record 10 July 1724 shows Thomas Marshall guardian to Margaret
Wainhouse, orphan of Dorothy Wainhouse, now the wife of Capt. Scarburgh. (Research of Court records by James H. Marshall) However, Margaret
was the daughter of Francis Wainhouse, Dorothy's brother. Her aunt, Dorothy, appears to have been her first guardian and Thomas Marshall on
his marriage to Patience became her next guardian.

Margaret Haggoman was named daughter by Patience Marshall in her will of
1765.
